Hi Michael, thanks a lot for this...will try !
As the import was not getting the result expected e.g. "all black" in styles list
the dxf-export file (from corel) tried to cover both bases. - it was not my intention to also have to colour the layers initially***.
i did it both ways as an experiment to see if it made any import-difference to getting colours on into MOI styles list.

My opinion is:

If the dxf shapes (or entities from corel) was coloured and/or the layer coloured and moi could intelligently pick up would be very flexible.
Or i guess it might need an import tweak with a few options.

** I do think colours by layer is the best approach for larger imports of many dxf entities or doing an import from
a more organised drawing,whereas byentity colour would be the icing on the cake - might be used when there
is less objects to import or less organised drawing.

Food for thought! I'd hesitate a guess MOI DXF importer could cover both bases.

Would you like me to give you any more flavours of dxf export from coreldraw?
I currently have 3 licensed versions X3, X6, X9.
